Note: Wallpaper .bmp files can be compressed using 7Zip to gzip format, or, for even better compression, you can use the LZMA utility (see \_ISO\docs\E2B Utilities\LZMA\ReadMe_LZMA.txt for details on how to use drag-and-drop to compress any file).
E2B (i.e. grub4dos) will automatically detect if any .bmp or text file is compressed and how it has been compressed (the file extension is irrelevant).The smaller the file, the faster it will load.E2B v1.72+ can also use JPEG encoded graphics files for backgrounds (save using MS Paint for correct format).
Set the Main menu background
Define different backgrounds for each sub-menu
1. Create a new folder at \_ISO\ANTIVIRUS\$$$$CONFIG and place your background bitmap in the new folder.
2. Create a \_ISO\ANTIVIRUS\$$$$CONFIG\CONFIG.mnu file with your settings- e.g. (assumes the bitmap file is in the same folder as the .mnu file)
Then copy the $$$$CONFIG folder to all sub-menu folders (except WINDOWS and MAINMENU). This would mean that any change you make to the sub-menu CONFIG.mnu file would need to be copied to all other sub-menus however. So instead, your CONFIG.mnu could call a grub4dos batch file - e.g.
Note: If you specify a different background in \_ISO\MAINMENU\$$$$CONFIG\CONFIG.mnu from the default \_ISO\MyBackground.bmp file (or the background file used in MyE2B.cfg), E2B will first load the \_ISO\MyBackground.bmp file (or default E2B file) and just before the Main menu is displayed, it will then load the background file from \_ISO\MAINMENU\$$$$CONFIG\CONFIG.mnu .
If you add 'call Fn.70 3' to the MyE2B.cfg file, then the user will see the default bitmap first during file enumeration and then the bitmap from $$$$CONFIG.mnu will be loaded when the Main menu is displayed.

# Show background wallpaper during file enumeration
\_ISO\MAINMENU\$$$$CONFIG\CONFIG.mnu (main menu image)
Background for AUTO (Direct) Menu (E2B v1.70+)
The file \_ISO\AUTO.bmp will be used as the background for the AUTO menu, if it is present. Note that you can compress the file using gzip or LZMA (best) or use a JPEG file, but the file name must remain as 'AUTO.bmp'.
The bitmap must be the same size as the Main menu bitmap (e.g. 800x600). Menu colours, etc. cannot be changed, only the background image.
If you want to set different colours for the menu text, then you must create a \_ISO\AUTO.g4b batch file - this will be used instead of the AUTO.bmp file - e.g.
Note that you could (in theory) also load a different sized bitmap by setting the graphics mode - e.g.
Backgrounds for Windows Install menus (E2B v1.70+)
If any of the following files exist, they will be loaded as a background wallpaper for the appropriate Windows Install menu. If the file does not exist, then the background will be unchanged from the previous menu.
- \_ISO\WINMENU.bmp (background for the Windows Install Menu - if any of the other Windows .bmp are used, this should also exist)
The bitmap must be the same size as the Main menu bitmap. You can compress .bmp files using gzip or LZMA, or use JPEG encoding (v1.72+), but the name+extension must not be changed (it must be .bmp).
If you only use \_ISO\WINMENU.bmp to change the Windows Install menu background, then all the Windows Install sub-menus will also use this background.
If you want to also change the colours (or other settings), then use a .g4b file (e.g. \_ISO\WINMENU.g4b) instead of a .bmp file - see AUTO section above for details of what to put in each file.
500 is x-coordinate, 0 is y-coordinate in the above example.
